Dell C1100 PCIe length limitations?

post #1 of 4
Thread Starter 
I'm trying to decide between a 6.61" long Powercolor HD 7750 and an 8.3" long XFX HD 7750 for my Dell C1100 server.

The Powercolor card will definitely fit as it almost exactly meets the specs of a half-length card (6.6"), but I'm not so sure about the XFX card. Unfortunately I don't have any single-slot PCIe cards to check with, and it's kind of hard to tell whether or not the card will bump into the outermost DIMM and/or the black heatsink by eyeballing frown.gif

I suggest you cut up some cardboard and make a box to test it.

Why is it that you are installing this GPU into a dell c1100?

Could be that he wants to use it as a main PC, or utilize some technology such as RemoteFX.

RemoteFX is the reason I have a Radeon 5450 in one of my C1100. I will, later today, open the case and measure the card and see how much free space I have behind it.

EDIT:
My Radeon 5450 is 6 and 11/16 inches in length (including the bracket -- 6 and 5/8, not including the bracket -- the bracket is 1/16 inches thick).

The PCI Riser card is 6 and 6/8 inches so my 5450 fits in there great. Behind the card there is nothing in the way for at least 4 more inches. The problem is not the length of the card, but the depth of the card because there is a heatsink on the motherboard and your SATA cables are hanging above that heatsink. Long story short, a 7 inch card should fit with no issues. Longer than that and you will have to worry about the GPU hittng the heatsink right under it and moving your SATA cables.

Thanks, both of you. Yeah, RemoteFX (or maybe VMware Horizon View, haven't decided yet) is the main reason.

Thanks for measuring. I guess a thin, PCB-only card like an NIC or PCIe SSD would be fine even if it's extremely long, but a GPU with a slot-wide cooler wouldn't have the necessary z-dimensional clearance.
